Looking for a list of all known public companies building on Ethereum

As the title says, I’m looking for a list of all the known publicly traded companies that are building on ethereum. So far I have not been able to find this. I’m wondering if anyone has come across something to this effect? It would be immensely useful in demonstrating to normal people outside of crypto that there is meaningful adoption taking place and the companies are taking this technology seriously - this lending legitimacy to it. Thanks in advance for the info!
